リプシッツ定数不要の遅延保証付きレディネス障壁による過駆動マルチロータの推力配分
Delay-Certified Readiness Barriers for Overactuated Multirotor Allocation Without Lipschitz Constants
各ローターの単調な閉形式応答を利用し、サンプル間でレディネス下限を保証するリプシッツ定数不要の検査法とフォールバックトルクを提案し、2〜40msの遅延下でも下限違反を防ぐことをヘキサロータで示した。

原文アブストラクト
Overactuated multirotors can produce the same wrench with many rotor-speed combinations, some of which leave the vehicle unable to change its wrench quickly, e.g., to reject a gust. Readiness barriers keep this ability, the readiness, above a floor, but only in continuous time; with sampled commands and varying speed-controller delays, the available robustness bound covers less than one millisecond. We remove this limit by exploiting the structure of the problem: each rotor responds monotonically and in closed form to its own torque, so the speeds reachable under uncertain switching times lie in a cheaply computed box, and the lowest readiness over that box sits at a corner known in advance. This yields a Lipschitz-free test that a command keeps the readiness above its floor until the next sample, plus a fallback torque that keeps the vehicle on a certified plan. In hexarotor simulations with 2--40~ms delays and $\pm2$~ms jitter, the filter never violated the floor. At $10\pm2$~ms, it matched a delay-compensating predictor within the design envelope and cost 2--30\% more tracking error beyond it, where the predictor alone violated the floor in 2 to 16 of 16 missions.
